cc6ec71b19 Sculpt: Wet paint area radius
This adds a new property to the sculpt vertex color paint brush to limit
the area of the brush that is going to be used to sample the wet paint
color. This is exactly the same concept as normal radius and area radius
that exist for sculpting brushes for sampling the surface depth and
orientation.

When working near color hard edges, this allows to prevent the color
from the other side of the edge to blend into the wet paint.

With 1.0 (the previous default) wet paint radius, as soon as the brush touches
one vertex of the other color, the wet paint mix color changes, making it
impossible to maintain the border between the two colors.

91694b9b58 Code Style: use "#pragma once" in source directory
This replaces header include guards with `#pragma once`.
A couple of include guards are not removed yet (e.g. `__RNA_TYPES_H__`),
because they are used in other places.

This patch has been generated by P1561 followed by `make format`.

438bd82371 Sculpt: Pose Brush option to affect loose parts
This option allows posing meshes with different disconnected elements
using the Pose Brush.

This is achieved by doing the following:
- Creating an ID per vertex that stores the connected component of that vertex.
- By using those IDs, one fake topology connection is created per vertex to the nearest vertex in a different ID. The maximum distance to create that connection is determined by the "Max Element Distance" property. These fake connectivity neighbors are used in the Sculpt API functions iterators, so all the algorithms of the Pose Brush can run without modifications as if everything was part of the same mesh.

In order to make this work, the "Connected only" property of the Pose Brush needs to be disabled. This will add an extra performance cost to the Pose Brush and its preview. To achieve optimal results, max element distance should be as low as possible.

84b94f9e7b Sculpt: Edge Automasking
This automasking option protects the open boundary edges of the mesh from the brush deformation. This is needed to sculpt cloths and it works nicely with the cloth brush.
It has a Propagation Steps property that controls the falloff of the mask from the edge.

Limitations:
- The automask is recalculated at the beginning of each stroke, creating a little bit of lag in high poly meshes, but it is not necessary. This can be fixed in the future by caching the edge distances, increasing a little bit the complexity of the code.
- The boundary vertex detection in meshes is not ideal and it fails with triangulated geometry, but it is the same as in the smooth brush. After fixing this, we should refactor the smooth brush to use the API and let the automasking option manually control the affected vertices.
- It does not work in Multires (it needs to be implemented in the API). The smooth brush in Multires is also not making boundary vertices.
- The falloff has a visible line artifact on grid patterns. We can smooth the final automasking factors several iterations, but it will make the initialization much slower. This can also be added in the future if we decided to cache the distances.

ff0124418f Sculpt: Hardness brush property
The hardness property moves the brush falloff towards the edges, making
the brush sharper.

This should be the intended way to control the brush falloff instead of
tweaking the falloff curve manually, as it can be mapped to pressure to
make the falloff variable during the stroke.
It is also a good idea to show in the UI that the custom curves is an
advance features and it should almost never be modified when sculpting/
painting unless you want to create some advanced effects. By modifying
the curves freely it is really easy to break the brushes and make them
produce artifacts. This needs to be done in a later after merging the
pending projects to reorganize all the brush properties accordingly.

4a373afa5f Sculpt: Cloth brush
This brush has a simple physics solver that helps when sculpting cloth.

- The mass and the damping properties of the simulation are properties of the brush.
- It has two additional radius control to limit the influence and falloff of the simulation.
- Masked vertices are pinned in the simulation, and it applies the sculpt gravity directly in the solver.
- The Cloth Brush has 7 deformation modes with 2 falloff types (radial and plane).

The brush can create the constraints only on the required PBVH nodes, so the simulation is isolated on high poly meshes. As long
as the brush size is not too big it should be possible to keep it real time.

Known issues:
- The way constraints are created is extremely basic and it creates repeated constraints. Maybe there is another way to create fewer constraints while keeping the simulation quality decent. This part can also be multithreaded. (As it is it works ok, but it could be better)

df45257ec5 Sculpt: Split normal radius and area radius
This enables an extra layer of control in the sculpt brushes.
For now it is enabled only in Scrape, but it should work in all brushes (like normal radius). In the future it may also be enabled in other brushes.
You can tweak in this property in the scrape brush to achieve a much better behavior when working on curve surfaces and control how much volume you want to trim. In most cases, it also fixes the bug where the brush keeps trimming in the same area without disabling accumulate.
It should be possible to fix some other artifacts in other brushes by tweaking this default property.

0314561684 Sculpt: Add color alpha controls to the brush cursor
Previously the alpha was hardcoded to 0.7. Now it is possible to control
the cursor alpha by changing the alpha color of the cursor color
property. New alpha default is 0.9. This, with the new saturated colors,
should make the cursor more visible on highdpi screens.

I also removed the cache location preview as it is too visible right now
with the new alpha and color values.

186bd1759f Pose brush: Smooth Iterations Brush Property
The smooth iterations of the pose factor were hardcoded to 4. This works fine in most situations when you are posing a low poly mesh, which is the main use case of this tool. I added the smooth iterations as a brush property in case you need to pose a high poly mesh directly without producing artifacts.
